Users Guide

For example, on a DHCP3 server, you can congure the assignment of a xed MAC-based IP address and conguration le by entering the
following lines of conguration parameters in the dhcpd.conf le on the server:
host S4810 {
hardware ethernet 00:01:e8:81:e2:39;
fixed-address 20.0.0.48;
option configfile "customer.conf";
}
Class-Based Conguration
By matching a part of the string from the vendor class identier option 60 string, the image, conguration le, or script le is sent in the
DHCP oer.
For example:
host dt-maa-z9000-11 {
hardware ethernet 00:01:e8:a9:81:a3;
fixed-address 10.16.151.175;
option tftp-server-address 10.16.151.209;
match if substring (option vendor-class-identifier,0,17) =
"TY=DELLNTW-Z9000 "; {
filename "tftp://10.16.151.209/FTOS-ZB-9.3.0.0.bin";
option configfile "ftp://anvltest:force10@10.16.151.209//
tftpboot/basic-l3-z9k <ftp://10.16.151.209//tftpboot/
basic-l3-z9k> ";
}
match if substring (option vendor-class-identifier,0,17) =
"TY=DELLNTW-s4810 "; {
filename "tftp://10.16.151.209/FTOS-SE-9.3.0.0.bin";
option configfile "ftp://anvltest:force10@13.4.4.4//
tftpboot/basic-l3-across-s6410-s4810_z9k.cfg";
}
}
Option 60 is also called vendor class identier. It has seven xed elds that have xed osets. The xed elds are:
• TY — denotes the type of the device
• HW — denotes the version of the box
• SN — denotes the serial number of the device
• ST — denotes the service tag of the device
• OS — denotes the Dell EMC Networking OS version in the device
• MD — denotes the method and is set to INT, when the discovers are sent through interface. This eld is set to BMP, when the
discovers are sent during bmp–reload
• US — denotes the user-dened string (a maximum string of 64 characters)
